如何使用C＃中的DateTime计算年龄 [ ^ ]。

// birthdate
        DateTime birthdate = new DateTime(1989, 1, 1);
        TimeSpan dur = DateTime.Now.Subtract(birthdate);

        int noOfdays = dur.Days;

        int noYear = noOfdays / 365;
        int noMonth = noOfdays % 365 / 30;
        int days = noOfdays % 365 % 30;

        //result
        string Info = noYear + " years " + noMonth+ " month "+days+" days";
